I've seen something like this a lot. It's really frustrating to see that those projects can't stick to their own words. Sometimes ICO got prolonged for months, with the spreadsheet not being updated regularly and then distribution happened 8 months later. Must be frustrating as hell for participants.
HyperQuant reserves the right to modify the terms of the campaign including but not limiting to the percentage of bounty channels allocation.
If they wrote "Rewards will be reduced if X campaign gets less than X numbers of participants" then we would agree with them. But they did not and their statement can be interpreted in a few ways and because of their bounty manager's mistake during the campaign and a few scammers, the team is denying the rightful amount of payment to those who deserve.
Next time don't join any campaign like this unless you're prepared to wait for your tokens for years (if they ever send it to you). This kind of rule is what makes me think they just use you for free marketing.
